Working with a child theme, when I change an appearance setting using the customizer, it displays in the preview but it doesn't take on the live page. This is a single-purpose theme and the settings I'm hard-coding into the child theme are probably going to be the ones that will stick but I'd like to know what's going on for future reference, as customizer support is one of the reasons I picked Themelia as a base for this project - easy prototyping for me, option for the site owner to tweak things later.
$parent_style = 'themelia';
wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'themelia-child',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
wp_get_theme()->get('Version')
);
